SPINNING-PRAIRIE STOP-MOTION.

Specification of Letters Patent.

Patented May 22, 191*.

Application filed. March 30, 1916. Serial No. 87,777.

To all whom it may concern:

Be it known that I, Errrnneun'r BnooKs- BANK, a subject of the King of Great Britain, residing at Bradford, in the county of York, in the Kingdom of England, have invented certain new and useful Improvements in Spinning-Frame StopMotions, of which the following is a specification.

The present invention has for its object improvements in those devices for the preventing of singles in the manufacture of yarn in which a weighted device is held in position by the multifold yarn at point be yond the junction of the component ends of the yarn, the weight of the device being such that it is supported by the multifold yarn but such that it overcomes the tensile strength of and breaks or otherwise severs by abrasion or cutting a single end or an end weakened by the prior breaking of one of the component ends.

According to the present invention the weighted device consists of a weight which simply rests on the wire or thread board of the frame and is held up by the end as it passes through the wire board or its equivalent. The invention is particularly applicable to those cases in which the component parts or ends of the yarn have but slight tensile strength.

I11 order that the invention may be fully understood reference will now be had to the accompanying drawings which show certain parts of a spinning frame diagrammatically with the invention applied thereto.

Figure 1 being an elevation,

Fig. 2 a side view,

Fig. 3 a plan view on the line IIIIII of Fig. 2,

Fig. 4 a detail view showing the preferred form of weight or weighted device by itself.

As shown in Figs. 1 and 2 a and Z) repre sent the front or final nip or forwarding rollers of the frame while 0 represents the wire or thread board. (Z and 6 represent the two ends which are being spun together while f represents the double yarn passing on its way to the spindle. In Fig. 4: the weight or weighted device is shown as consisting of a small piece of wire or the like 9 bent in the form of a U. This, as is shown in Fig. 3 is placed on the wire or thread board 0 with its limbs one on each side of the doubled portion 7 of the end as it passes through the pot eye 72. in the board 0. So long as the two ends (Z and 6 remain whole and are united properly to form the double portion f the device 9 is held in the position shown in Fig. 2 and in the upper portion of Fig. 3. Should however one of the ends (Z or a break then the tensile strength of the single thread which tends to pass through the pot eye is so weakened that it can no longer support the weight 9 so that it is always broken down with the result that the spinning of a single is absolutely prevented. On this breaking of the single taking place the device 9 will slide down the board against the ledge 70 as shown in Fig. 3 within easy reach of the operative.

When it is desired to piece up the broken ends the weight g is removed or raised by the operative, the end pieced up and then the weight 9 replaced in the position as above described. I

Naturally in those cases where the single ends (Z and e are of considerable tensile strength the weight of the part 9 might have to be so great as to make the invention impracticable, and while the shape of the device above described is considered the most efficient and practical. it will be obvious that the device can be given any shape whatsoever so long as it merely rests on the thread and on fracture of the thread slides down the ring board.

I declare that what I claim is 2- 1. A multifold yarn spinning frame stop motion comprising a frame, a wire or thread board thereon, and free, loose, weighted collars supported by the multifold yarn passing therethrough and adapted to sever the remaining ends of said multifold yarn when an end breaks.

2. A multifold yarn spinning frame stop motion comprising a frame, a wire or thread board thereon, and U-shaped collar weights supported by the multifold yarn passing therethrough and adapted to sever the remaining ends of said multifold yarn when an end breaks.

A multifold yarn spinning frame stop motion comprising a frame, a wire or thread board thereoin and bent Wire Weights de- Eachahle 1 1 oln hu t supportedhy the nnlitl- ETHELBERT BROOKSBANK 01d yain passlng iherethrongh and adapted 5 to sever the remaining ends of said multifold yarn when an end breaks.

In Witness whereof I have hereunto signed my name this lith day of March, 1916, in the presence of two subscribing witnesses.
